It will probably be dismissed.

The judiciary in Argentina is largely at the beck and call of Milei's political godfather, former president Mauricio Macri, who uses them to put pressure on his political enemies (largely kirchnerismo), and also makes them quietly drop most lawsuits against him or his allies.

Now, to be clear, it's Macri (not Milei) who has the courts in his pocket, and lately they have a strained relationship, because Macri wants better positions in government for his cadres, while Milei is instead poaching them for his own party. So it's very likely this whole mess will be just a way for Macri to remind Milei who's who, and get a few favors, after which the whole thing will go away.

I'd love to be wrong about this, and for Milei to face the music, but I don't think I'm wrong.
